The nanofluids flow through a copper helical coiled tubes in the laminar flow regime. Steady state heat transfer experiments of helical coiled tubes were performed for the relevant parameters in the following ranges: the input temperature in the heated section T=60℃, the flow rate of nanofluids =65~295 (mL/min) ，the weight percentage of the Cu-DI water nanofluids Cw=0.092wt%、0.138 wt%、0.292 wt%， and the weight percentage of the Cu- ethylene glycol Cw=0.107wt%、0.184 wt%、0.388 wt%。
The results indicated that the copper nanoparticles had profound and significant influence on overall heat transfer coefficient in the nanofluids with different concentration.For example,the Cu-DI water nanofluids could increase the overall heat transfer coefficient 19% than that of pure water，the Cu- ethylene glycol could increase up to 28%.
